HOOD HINGE FOR AUTOMOBILES.

Application filed July 3, 1920. Serial No. 393,797.

To all whom it may concern:

Be it known that I, GUiDo G. BEHN, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Hood Hinges for Automobiles, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates particularly (to a hood-hinge for automobiles, although it may be capable of use for other purposes. As is well understood by those skilled in the manufacture of automobiles, difliculty has been experienced in the past in producing a hood-hinge which will withstand the rough use to which it is subjected and will not render the hood unsightly. Since the hood is at all times directly in front of the drivers eye and is a part of the car to which attention is usually first directed, it is most important that it shall have a neat and pleasing appearance. He-retofore, it has been customary to use a line of rivets or a series of spot-welds parallel with the pintle of the hinge to secure the hinge to the adj acent parts of the hood, and these have interfered with finishing the hood, since the rivet heads project, and the spot-welding leaves indentations or spots where the enamel does not adhere well.

My present invention obviates both of these objections and leaves a hood the entire surface of which is unobstructed and can be perfectly finished.

The invention will be fully understood from the following description when taken in connection with the accompanying drawings, and the novel features thereof will be pointed out and clearly defined in the claims at the close of this specification.

In the drawings, Fig. 1 is a side elevation of the hood of an automobile to which my invention is applied.

Fig. 2 is a section on line 2 of Figure 1.

Fig. 3 is a section of one hinge member ready to be secured to the hood.

Fig. 4 shows the hood and hinge member secured together.

Fig. 5 shows the parts shown in Figure 4 completed and ready to be assembled.

Referring now to the drawings, I first cut a suitable piece of sheet metal and form the same as shown in Figure 3 to form one hinge member. As will beseen, this hinge member 11 is somewhat U-shaped in cross section, having two legs a and b which collectively constitute the leaf portion of the hinge and a cylindrical or tubular portion 0, which is interrupted at intervals in the wellknown manner. When the parts are assembled, the tubular portion receives the pintle 12. One hood member 13 is then bent to an angle to form a flange d along its edge, as shown in Figure 4, and it is then superposed in proper position on the hinge member with the flange d in contact with the leg 7) of the hinge member. The parts are then secured together in whatever manner is most convenient, as for instance, by spotwelding or riveting.

In the drawings, I have shown a spotwelding at the points 14, 14. Spot-welding is convenient because is does not require any punching operation and secures both legs of the hinge and the flange of the hood to gether at a single operation. The parts are then in the position shown in Figure 4. Thereafter, the flange d of the hood member 13 is bent by rolling or otherwise to the position shown in Figure 5 in which the surfaces are practically in contact with each other and as nearly parallel as the nature of the material will permit.

The other hood member 15. and hinge member 16 are similarly constructed and secured together and the two hood members assembled by the insertion of the pintle l2.

l/Vhen completed, the exterior surface of the hood is left entirely smooth and is not marred by any spot-welding or rivet heads, so that the enamel or paint can be applied uniformly to its entire surface and its surface can be rubbed and polished with perfeet ease. The above described method of making the hinge herein claimed forms the subject matter of another application filed October 8, 1923, Serial No. 667,147.

What I claim is:

1. The improved hood-hinge comprising U-shaped hinge members of sheet metal and hood members the edges of which are folded upon themselves into U-shape and are superposed on the legs of said U-shaped hinge members and secured to the outer side thereis folded inwardly upon the exterior portion of so that the exterior of said hood men thereof into U-shape, said inwardly folded bers have a smooth appearance. portion being superposed upon the outer D 2.
